RAUC v0.1.1 released

RAUC is making progress, and my colleagues Enrico Jörns and Jan Lübbe finally
pushed out a new release today that reflects what happened during the last
months. Updating embedded linux systems in the field in a secure and robust way
becomes more and more important; we had many interesting talks with our
customers during the last time, and some of the new ideas are already finding
their way into the codebase. However, there is still a lot of work ahead, and
if you have more ideas, either drop us a note on the community channels, send
patches or github pull requests, or ask for commercial help!
